WIRE MAT.

SPECIFICATION forming part of Letters Patent No.359,235, dated March 8, 1387.

(No model.)

To all whom, z may concern:

Be it known that I, JOHN Tvn, of the city `of Toronto, in the county of York and Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Wire Mats; and I do hereby declare that the following is a full, clear, and exact description of the same. 4

This invention relates to improvements in to that class of wire mats which are used as foot Scrapers andwipers and like articles. Its object is to lighten the construction and eheapen the manufacture without impairing the efficiency or durability.

.t 5 In all other wire -door or foot mats of which I am aware it has been necessary not only to have a woof of crosswires linked or intertwined with the warp or longitudinal wires of the fabric, but also a heavy iron frame and 2o crossing or intersecting bars to aiord the necessary stiffness and rigidity to the article. Again, in other mats of this class the stretching or adjustability of the coils has not been provided for, but, on the contrary, the outer ends of the wires have had to be permanently twisted by hand around the frame, a work at once tedious and expensive, besides impairing the mat in its appearance. By my invention all these difticulties are overcome, and I likewise produce a mat the wire fabric of which can be quickly renewed at trilling expense,

should it become damaged from any cause, while preserving` the same framing or holdfast devices.

To this end my improvements consist, mainly, in the combinatiomwith longitudinal or diagonalwires linked together, of clampingirons gripping and holding the ends of the coils, and of side rods connected with the end 4o clamping-irons in such manner that the wires may be stretched should such adjustment become necessary.

Certain details of construction and combinations of parts are also included in my inven-v 4 5 tion, for full comprehension of which reference must be had to the following detailed descrip' tion and accompanying drawings, forming part of this specification, similar letters of reference indicating like parts.

5o In the drawings, Figure 1 is a plan, partly in broken section, of a mat constructed ac eording to myinvention, Fig. 2, an edgeview, partly in section, illustrating another way of applying the stretching-rods; Fig. 3, an e11- larged sectional detail showing the way in 5 5 which I usually connect the wires with the end clamps, Fig. 4f, a perspective view of the two parts of my clamps, and Fig. 5 illustrates a modification.

Referring to Figs. l, 2, 3, and 4, A A are a 6o series of coils, made from wire of suitable gage, each linked with its neighboring coil, (in substantially the same manner as the wires of the well-known coiled or woven wire mattresses) the'ends of each strand being held by clamps 65 B B. These clamps are by preference of rounded or oval shape, and are made in two sections, b If, with a hollow center, b3, the edges Z1* ZI, which come together, being flat, featheredged, or of other suitable configura- 7o tion. I usually connect these sections Z1 b2 by means of curved hooks b5, attached to one section and entering curved holes Z)6 in the other section, as seen in Figs. 3 and 4, thus forming a hinge at one of the joints and allowing the opposite meeting edges to separate and admit the ends of the wires A A to the interior of the clamp, as shown in Fig. 3, said wires being liattened, if found necessary, at this point to allow a close joint to be formed. 8C'

'bT bT are threaded holes in one section of the clamp, into which screws bs are inserted to .hold the whole firmly together; or I may use rivets or other like means of fastening in place of the screws. 35

C C are longitudinal rods, one at each side of the mat running from one clamp to the other, and by preference passing through the outer wire coils. These rods are forthe purpose of stretching the wire should adjustment bego come necessary, being provided with screwthreads at each end, as shown at c ci, and having nuts c3 cl working on these threads and aror channels between the coils parallel to the clamps, thus making the scrapers I) run directly across the mat, whereas they are diagonal in Fig. I.V This modified construction will necessitate the looping of some of the wires around the stretching-rods C, as shown at E, these loops being large enough to allow said rods to pass freely through them and slide thereinwhile thestretchin g is bei ng performed. My end clamps and continuous stretching rods may be used with other forms of mesh, it being apparent that I am not limited to the manner of weaving above described.

p I am aware that there are many devices in use for stretching the wire fabric of springbeds, and I am also aware that clamps consisting of two flat pieces of wood have been used for holding the ends of the wire fabrics in beds 5 but I do not lay claim to any of such devices in themselves or to the idea of stretching a wire fabric, broadly speaking.

Having thus described my invention in such manner that persons skilled in the art may make and practice the same, I beg to state that what I claim is as follows:

1. A wire door or foot mat, composed of a series of coiled wires forming amesh, end clamps holding the ends of said wire mesh, and stretching-rods extending between said clamps and connected therewith, said stretch ing-rods also passing through the extreme outer coils of the mesh at the sides of the mat, substantially as set forth.

2. The co1nbination,in a clamp for wire mats, of two sections, bb2, hollowed in the center, hinges or hooks b5, and screws or rivets bl, substantially as and for the purpose specified.

Toronto, Canada, June 3, 1886.

JOHN TYE.
